Anyone gone from 4 to 6?

Interested to hear opinions between a 4 and a 6 series. Currently trying to decide between the two (435i vs 640i), apart from size (and weight), what are the other differences (quality, reliability, ride quality, etc)?

Doing this in 2 weeks in Germany with European Delivery. Happy to update then. 2013 335is vert to 650i vert. I bought it due to all of those reasons you listed. We will see if I was right.

Coming from a 328, through a 528 to a 640. Also test drove a 435 GC before settling on my 640. I recommend you drive them too.

There really was no contest in my mind. Fit/finish/feel was far superior in the 640GC. 435 felt small, quick, drove nice. But the 640 put a huge smile on my face....

I do wish the 640 had a trunk like the 435GC, that was a great feature.

I have a 4 gran coupe and a M6 gran coupe.

Outside of the almost $70k price difference between the two, the 6 is more of a BMW than the 4, but on long hauls Id rather take the 4, cause of the extra trunk/hatch space, but the M6 is on a whole other level.... TOP of the BMW food chain IMO

If you can take the price, get the one you want, but drive em.

I've gone from a 335i vert (E93) to 535i (F10) to 650i GC. The 6 is larger than the 3/4 series and can have a much higher-end interior depending on how you equip it. In the U.S., it looks like the 4 is limited to Dakota leather options. The 6 gets you options for Nappa or Merino leather which has a much nicer feel. The layout of the 6 is much more intimate in my opinion. You get more powerful engine choices with the 6 series. A more powerful 6-cylinder or the glorious 8-cylinder. Add on the M-Sport Edition with LCD gauges and LED highlights for more exclusive tech options.

Basically, the 6 is more expensive, has a nicer interior, the best BMW tech this side of the i8 and 7-series with more powerful engine choices compared to the 4.

Compared to the 5-series, I feel the 650i is much more fun to drive. Way better driving dynamics in my opinion. It rides much lower and feels so much more connected to the road. Put it this way, I test drove the F10 M5 and the 650i back-to-back. I chose the 650i because I felt it drove better and a much more connected feel.

But keep in mind the 6 is also much bigger than the 4 series. You will absolutely be able to feel the much bigger car when you drive it. Is that best for you? It's up to you to decide.

Wish there was an M4 Gran Coupe, would make the direct comparison to a 6 GC closer.

Agreed! I have a 2012 550 but the minute the m4 gc becomes an option I will be checking it out for the possible change.

Had the F10,F30,F13 ... It depends on your preference.. do you feel stronger towards the luxury factor and comfort? If you love spirited drives it's hard to contest with the weight and size of the 4 compared to the 6.

Having said that my girl always gives me grief for letting go of the 6..

Drive them all. Had a 550i and went to a 650ix and now am looking to go back down to a 4 or 5 again. 6 series is very luxurious but it is a big car and drives as such. That and around town dynamics which is almost 90% of my driving don't lend itself to the size of the 6. Granted I have a 650ix GC. But it is a big and long car. However for long distance cruising or for a big guy probably would work out well. I am a driver and like HPE and track events too and no 6 outside of a M6 would do well there.

My wife will kill me for the bath I will take on selling my 650ix GC early but she knows that luxury isn't my forte and I love driving my cars and performance thus she'll understand but yes it depends on what you want. Choose carefully...one thing I will say..the increased number of choices from BMW from 1,2,3,4,5,6,7 and possibly 8 make it easy to confuse each ones attributes at times. 640/650 look sporty but are truly performance cars? Outside the M's not as much I think after owning one. GL

There's no comparison between a 435 and a 6 series. The 6 is just far superior and luxurious. The only fair comparison is with an M4. I had a 2015 M4 for almost 3 mos and I totaled it. Jumped from a 325i and I guess I couldn't handle the power.
I decided to go for a 2015 640xi coupe instead. Because I'm in NY and I don't want to deal with the hassle of a rwd vehicle anymore. The 6 screams luxury! But M models are simply AMAZING. Apart from the abysmal difference in power and performance between the M4 and the 640, the m4 coupe is bigger than the 640 coupe (believe it or not). I was able to fit 4 people with PLENTY of leg room in the back of the M4. I highly doubt anyone would ride comfortably in the back of a 640 coupe...
I hope this helps.

Wow... Sorry to hear you totaled your M4. can you share with us what exactly happened if you don't mind?

I agree with you about the room of 640. All 6er coupe including M6 are the same. The 4 er has more room.

Yes...went with a 2015 M3 w/DCT and a few options and am 110% happy. It's definitely the sweet spot here for me. More sporty than the 6 by far and also the 550 I had. Not as luxurious and I do miss a few options (mainly comfort access-had gotten lazy and HUD-is repeated in the lower dash in my car so not as bad). But so far yes great move from 6 to 3 which I don't regret as I didn't need all that space and size honestly and the 650ix GC just became too unwieldy for me!

Killing me - I'm so tempted. Love my 650 but the tight turns I need to make in my neighborhood require me to confirm a car is not coming towards me in the direction I'm turning, since I need two lanes just to make right turn. Congrats on your purchase - I am going to try to hold off for the 2016s

Im thinking about going from my 650 coupe to an M4 next time around.. The power they are making tuned and bolt ons is ridiculous and can be had for a lot less than an M6. Then again I'm also going to look at the M5 and that's gonna be a hard choice. The 6 series is up on the flagship of the BMW series and nothing compares to that driving machine and how large of a coupe it is! But the wonderful thing about leasing is that you get to try out a new one every 2-3 years and keep things fresh with new models and different aspects of luxury and sport. Long live the king of the ultimate driving machines, BMW!

Yes it may fit for you. I had an M5 to choose if I so chose but in the end I looked at it from an all around standpoint to and the cost of the M5 and the pros/cons of driving dynamics, space and when I read most of the reviews...a lot of folks basically said while powerful and luxurious and fast even with the competition package the M5 wasn't as sporty as it should have been or they expected especially when compared to previous models e39 M5 and e60M5 and that the M6 actually drove better! So that was a dilemma from what I was experiencing in my 6 series grand coupe to consider. Ultimately I looked back at the new M3 and M4's and found that hell its putting out more torque and better performance and driving dynamics than its bigger brother for less money and more fun and THAT was the equation I was looking for. Something I loved to drive and could be driving and taken to the track IF I wanted or a HPDE and just enjoyed too without worrying about the mass/weight, etc. Also I am luckly I just recently acquired a CPO '10 X5M for hauling azz and stuff fast so I am good for that category. Add to it the '14 Cayman S 6spd for when I really want to attack a track and it was an easy solution...ditch the 650ix GC! Never looked back!

I'm as much a fan of the M3/4 as the next guy. These cars are after all BMW M cars. No doubt they are lighter and "sportier" than the M5/6 and if that's what you are looking for, the M3/4 still rules.

But there is no way the S55 puts out more torque than the S63Tu. As published the S63Tu puts out about 100lb-ft more. As dyno'ed there's an even greater difference.

I had a 3 (F30)...design and everything else pretty much like the 4 with the exception of 4 being a bit wider and lower...that's seriously just about it!
So I would never buy a 4...
I would however move up to 6 provided:
1) I could afford the 6
2) the 6 wasn't going to be outdated in 1-2 years;
So What I would do, if I were you (assuming you have a 4 already), is keep my 4 now as it is the newer Gen of BMW at least and move up to 6 when the new Gen (G chasis) comes. That's me talking of course...opinions are different...
my problem is, I can't pay for a $120K vehicle (6) knowing that it will be outdated in less than 2 years...because while I'm still heavily paying interest and installments on this 6, a new G gen 6 will pass by me in 2017...and that my friend, is a heavy picture I am not willing to paint!

That's why they offer lease programs.. Keeps you in a new car every 3 years and you are paying lower payments than owning one outright. It works for me cause I don't want to buy cars, I want to lease them and give them back, either way you're spending the money so why not do it in a brand new model every time? A car should never be looked at as an investment.

To be exact 130 ( ~30%) more torque (576 vs 446) measured by Dinan as a well-known tuner in US ... and since both car have the same gear ratio (if both have DCT) while M3/M4 have almost 10% shorter FD ratio (3.46 vs 3.15), still M5/M6 transfer more torque (~17%) to the rear wheel ...

Yes more torque and yes the driving dynamics between the two cannot be different. The new M3/M4 cars are lighter than their predecessors while the M5/M6 have gotten heavier and larger and more complex. Not that they still don't do the job but having driven all three chassis now F10, F06 and now F80; I cannot but help to say that the smaller chassis does drive better dynamically and is more nimble as expected that the larger chassis just cannot do as well. Yes the M6 is a brute as is the M5 but they still cannot overcome the physics portion of the equation they need to deal with as well as the smaller BMW. Much more torque is needed to move the large mass of the larger 5 and 6 series M cars. BMW had done I think a great job of giving each owner something he/she seeks its just their job to figure out which ones are important to them as none of them do all things well. But the M3 to me brings it back and closest to the driving experiences of my e46 and e92 M3s.
